The human species has dramatically changed its mode of life over the past thousands of years, while no animal species has done so. Understanding that quality which sets us apart (called by such names as "intelligence," "reason," "rational thought," or sometimes, simply "language") is not a question for idle philosophers: it is a key political question in our time. Jason Ross discusses the aspect of human creativity that is, by its nature, not possibly included in any scheme of "artificial intelligence" -- the resolution of contradictions through the creation of higher concepts from which the formerly different perceptions no longer contradict each other. Taking historical examples from Cusa and Kepler, and treating the current problems of quantum physics, we'll arrive at a conclusion which demonstrates why economics, rather than mathematics, is the greatest of sciences.
